Not always... if it were possible, I suppose that larger diameter and thinner and less weight would always be better. But usually, there are losses and gains.

I cut a box.

imola aka the rim 15 " .



ronal with rim 14 . "



There is space and fits a finger.

a way to hold the cover can be with screws.



I 'm thinking it's better steel rims .

and look for a cover with small holes.
plug the holes with adhesive tape .



covers use previous steel wheels . on aluminum wheels.

consider this...

How long a tire (lasts/performs/cost) may out-weigh the mpg dollar advantage...

Two of the tires were bad. I've changed some 175 / 65R14 primewell ps880 .
175 / 65R14 is more popular.
I can save by switching the measure 165 / 70R14 ?
